•
The verification pin should be placed at 2000 ±500 mm from the
RTG Reference Point.
•
Measure the distance from the top of the bottom plug to the bot-
tom of the tank, see Figure 1-16. This value will be used for the
calibration of the RTG:
•
Zero level at tank bottom
: adjust the Calibration distance
value until the displayed level (at the calibration ring) is equal
to the distance from calibration ring to tank bottom (see Fig-
ure 1-16).
•
Zero level at calibration ring
: adjust the Calibration dis-
tance value so the displayed level is equal to zero.
